My invention relates to improvements in the class of safety razors in. which a stack of blades is maintained in position to be successively inserted in a blade holder, as occasion may require.

One of the objects of the invention is to provide al blade holder having a guard, means to retain the blade in shaving relation to the guard and means to adjust the position of the guard relatively to the blade edge for shaving and to retain the guard in adjusted positron.

Another object of my invention is to provide improved means to permit insertion of the stack of blades in a magazine 4or container and to retain them resiliently therein. Other objects and advantages will appear in the following description.

My invention com rises novel details of improvement that wi l be more fully hereinafter set forth and then pointed out in the claims. Y

imilar numerals of reference indicate corresponding parts in the several views.

The numeral 1 indicates a blade holder, and at 2 is a handle shown provided with a reduced portion 2a to whlch the blade holder is pivotally attached. I have shown a screw 3 pivotally connecting the blade holder and the handle, whereby the blade holder may be turned .at an angle to the handle for shaving, (Fig. 1), and may be turned parallel to the handle to receive and discharge blades, (Figs. 4 and 5). The blade holder has a relatively ilat seat 4 upon which the blade 5 may rest with its cutting ed es extending beyond the seat for shaving. uards for the blade edge are indicated at 6, which guards are shown provided with comblike teeth at 6a in proper position relatively to the blade edges to guard the latter. The guards 6 are connected to the blade holder so as to have movement relatively to the corresponding blade edges, the guards being shown attached to the blade holder material by the connectin pieces 7, and due to resiliency of the meta ...the guards may be adjusted toward and from the blade edges. I have illustrated screws 8 operative in threaded bores in tbe guards, adapted to be rotated against the body of the blade holder for adjusting the guards nwith respect to the blade edges, (Fig. 2). At 9 is a retainer for the blade to keep the latter pressed against the seat 4. The retainer is attached to the blade holder, as llvrivets orv screws, at 9', (Fig. 1) and is of resilient material so as to overlie the blade at the free edges 9a of the retainer, said edges being suitably spaced from the seat 4 of the holder to receive the blade in the space therebetween, ressure of the retainer upon the blade kee mg the latter on its seat. The corners of t e retainer are shown secured to posts 6b near the ends of the guards. To permit the blade to slide along the seat 4 of blade holder 1 and to retain the blade in shaving position I provide a plate 13 that is located between seat 4 and the adjacent end of 10@ handle 2, which plate is provided with tapering projections 14 that are adapted to pass through openings 1a in the bla e holder at the seat 4 and t rough registering openings 5a in the blade, (Fig. 8). The plate 13 is shown provided with outwardly pressed spring-like fingers or tongues 13a that bear against the wall 1b of the blade holder, Fig. 5), to normally push the plate toward the adjacent end of handle 2. The extreme end of the handle is shown flat at 2b to bear against plate 13 for pushing the plate to extend the projections 14 through the openings 1a in wall 1b and through the openings 5a of blade 5, (Fig. 3), and the adjacent portion 2c of the end of the handle is rounded to rock a ainst the plate 13, whereby the latter may7 ear against the reduced edge portion 2d of the handle when the holder and the handle are in parallel relation, whereby springs 13a will push the plate 13 away from wall 1b to cause withdrawal of the projections 14 from the blade, (Fig. 5). When the parts are in the position shown in Fig. 5 the blades will be free to ,slide along seat 4 of the holder, and when a blade has been placed in proper position upon the holder and the latter is turned crosswise respecting the handle, the plate 13 will be pushed toward the wall 1b and the projections 14 of said plate will Apass through the apertures 5a of the blade to position the blade and to retain the latter in shaving position on the seat of the blade holder, (Fig. 3). The resiliency of the springs 13a, tending to press the plate 13 against the adjacent end 2b of handle 2, will serve to retain the blade holder in shaving relation to the handle, (Fig. 3).

The handle 2 is provided with a magazine or compartment 15 to retain a stack of blades in such position that they may be ejected into the blade holder as required. The magazine or compartment 15 is shown open through opposite sides of the handle, and covers 16 and 17 are adapted to close and open the magazine, as in the nature of doors. The cover 16 is shown slidably attached to handle 2, for which purpose the edges of the cover are fitted in grooves in the corresponding edges of the handle, (in dove-tail fashion), as indicated at 18, (Fig. 7), and in the form shown in Figs. 1 to 11 the cover 17 is also slidably attached to the handle, in dove-tail fashion, as indicated at 19. Dents at 20 in the covers permit a finger to push the covers to an open position. The end Walls of magazine or compartment 15 are shown provided with projecting guides 21,21awhich receive notches 5b at the ends of the blades to retain the .latter in proper position in the magazine with their edgesout of contact with the handle, (Fig. 7) The guides-21, 21a are shown of different contour to engage corresponding notches 5b in the blades to assure the desired position of the blades in the magazine to receive the projections 14. Spring catches 22 carried by the end walls of the magazine or compartment 15 are adapted to engage a stack of blades when the latter are against the close cover 16 to retain the blades. A. spring 23 bears against the stack of blades in the magazine to retain the latter in snug position pressed against cover 16. In the form shown in Figs. 1 to 11 the spring 23 is shown pivotally supported by a pin at 24 within the magazine or compartment 15 so as to swing through an open side of the latter to permit insertion of a stack of blades into the magazine, (Fig. 9). Said spring may be swung back through the opening into the magazine to bear against the blades therein and the parts will be retained. when the cover 17 is closed, as indicated in Fig. 5, the spring pressing the stack of blades against cover 16. The spring 23 is shown provided with a flat portion 23 Vto bear against the cover 17, and with a reversely extending free portion 23 to bear against the blades, (Fig. 5), so organized as to follow the stack of blades as the latter become reduced in quantity in the magazine.

At 25 is' an ejector for the blades adapted to be reciprocated within the magazine to push blades therefrom through a space 26 between the adjacent portion of the handle and cover 16 into the blade holder, (Figs. 5, 9 and 12) The ejector 25 is guided'to slide within magazine or compartment 15 and is shown comprising a flat blade ejecting portion 25 and spaced side portions 25 that are guided in recesses 27 in the side walls of the magazine, (Fig. 7). The ejector 25 is shown provided, at its outer en d, with an enlarged head 25a for manipulating it, which head 1s adapt-v ed to oppose and stop the covers 16 and 17 `when the latter are slid outwardly respecting the magazine, (Fig. 9) The ejector is shown provided with an opening'28 that is adapted to engage a projection 29 struck out or projecting from a curved spring 30 located in a recess 31 in handle 2, (Fig. 9). When the ejector is pulled out the projection 29 will enter the opening 28 to limit the outward movement of the ej ector, and when the latter is pushed inwardly it will slide over the forwardly inclined projection 29.

In the form shown in Figs. 12 and 13 the cover 17 is pivotally connected to the handle, at 32, to be swung away from the magazine or compartment` 15 to permit insertion of blades 5 therein. A spring catch 33 is retained by a pin ,34 in a recess 35 in the handle in position to retain the cover 17 closed. When the cover is to be opened the spring catch may be pushed away fromthe position shown in Fig. 12 to release the cover. In said form the spring 23 is'shown attached to cover 17 by means of a rivet 36 so that when t-he cover is swung back to the closed position the spring will bear against the stack of ushed into the magazinesro vmi

lfilades in the magazine for the purpose beore described.

At 37 is a guide for the blades, located near the blade deliver side of the holder to guide the blade being ischarged, (Figs. 1, 5a and 11). The guide 37 is shown comprising a resilient wire having a mid-portion 37 secured by a screw 38 at the end of the blade holder, (Fig. 1) from which portion 37 arms 37a extend, substantially in U-shape, providing the spaced guide-members 37 b, between which a used blade may slide when being ejected from the holder, (Fig. 5a). When a blade advances from the magazine it will push a used blade from the holder, and since the two blades are in contact end to end the guide-members 37b, by guiding the blade that is being discharged, will cause the latter to keep the cutting edgesyof the new advancing blade out of contact with the blade holder as the new blade slides to shaving position along seat 4. The guide-members 37b also tend to dull the edges of the discharged blade'to resist cutting the lingers of the user.

. In order conveniently to handle a stack of blades I have illustrated a holder in Fig. 8a shown comprising a spring Wire having a loop-like resilient handle portion 39 and two outwardly extending arms 40 having lateral projecting portions 41 adapted to bear upon the upper blade and provided with relatively short laterally extending end lugs 42, the portions 41 being adapted to be passed Y through the registering openings 5a of the blades with the lu engagmg the lowermost blade and retain t em in a stack. The handle 39 may be gripped and the stack of blades may be set into the. magazine or compartment of the handle 2 without danger of touching the cutting edges of the blades, and by squeezing the handle portion 39 the holder may be released and removed from a stack of blades leaving the latter deposited in the magazine. a

When a blade is to be inserted in the holder the latter will be turned parallel with the handle, the ejector 25 will ybe drawn out permitting the endmost blade of the stack to bear against the cover 16 in register with the ejector, and then the latter will be pushed inwardly to push the blade from the magazine through space 26 into the holder, said blade ejecting from the holder a used blade, (Fig. 5). The sliding of the blade in the holder will be permitted because the projections 14 will be out of the path of the blade, as in Figs. 4 and 5. When the holder is rotated to the shaving position the cooperation of the end portion 2b of the handle with the plate 13 will cause the projections 14 to pass through the openings 5a in the blade toretain the latter in shaving position, (Fig. 3). By having the covers 16 and 17 movable with respect to the ma azine or compartment 15 the insertion of t e blades therein is facilcovers are opened.'

itated, as well as their removal therefrom when desired, and also the compartment will be free to be cleaned and wiped when the By having the spring 23 pivotally carried by the. handle said s ring may be readily manipulated indepen ently of the manipulationof the stack of blades, which will facilitate o erations.
